Quantum information theory is a rediscussion of
quantum theory in an information theoretical context and at the same time a
generalization of classical information theory to the quantum world. This
module provides an introduction to the mathematical and conceptual foundations
of the theory, its applications and the most important quantitative
questions. Subjects to be discussed include: states and effects, ordered
vector spaces, tensor products, correlations and entanglement, Bell
inequalities, channels, positivity and complete positivity, estimation theory,
quantum cloning, quantum error correction, channel capacities, distillation of
entanglement, and entanglement measures.
